ECOL 2050 lab 1 -

Randomly selected individuals were observed on campus walk in York University. The Researches observed 3 variables: gender, glasses, and hair colour. Gender was recorded as observed. Glasses present were recorded as any type of glasses (sunglasses, corrective glasses) that were visible on the individual. Finally, hair colour was recorded as observed, and if there were multiple observable colours the individual was questioned about their natural hair colour. 25 individuals were recorded. When a group passed by only one individual from the group was recorded to avoid biased sampling.

研究人员在约克大学（York University）的校园步道上，对随机选取的个体开展观察研究。本次研究共记录三类变量：性别、眼镜佩戴情况与头发颜色。其中，性别以现场直接观察结果为准进行记录；眼镜佩戴情况记录个体可见的任意类型眼镜（太阳镜、矫正眼镜）的佩戴状态；头发颜色同样依据现场观察结果记录，若个体存在多种可观测的发色，则通过询问确认其原生发色。本次研究共记录25名个体，当有群体经过时，仅选取其中一名个体进行记录，以规避采样偏差。
